For the past couple of years I used a pair of 1.5 TB Seagate ST 31500541AS hard drives configured as RAID 1. They both gave reliable service. I donít see them listed.

Last week I switched them out for a pair of 2.0 TB Seagate ST2000DM001 hard drives configured as RAID 1. I donít see them listed either. They formatted to full capacity and passed both the SMART and scan disk tests. 1.1 TB of data copied back to them @ 19.1 MB/sec. over GBit Ethernet.

The first list below contains published D-Link approved and verified Hard Drives (HDDs). The second list contains HDDs tested by D-Link forum community end users. If you would like to contribute a HDD you personally tested to this list, please post the HDD make/model/capacity, configuration, length of time in use, and observations (e.g. stability, performance, etc) as a reply to this thread.

*Disclaimer: Hard Drives (HDDs) categorized as tested by end users were neither internally tested nor verified by D-Link. As such, users who opt to purchase HDDs on this list categorized as tested by end-users for their ShareCenter DNS-320 do so at their own risk.

Firmware Requirement for High Capacity HDDs

Hard drives with capacities greater than 2TB are only compatible with Firmware version 2.01 and above. Firmware v2.01 is the first release for the DNS-320 designed to handle advanced format addressing (AFD) required to support high capacity HDDs.

HUA723020ALA641 (2TB)ST3500630AS (500GIG)Current NAS Firmware Version 2.05Firmware Date 05/07/2014Using standard and both are just fine after getting them full. I have several of the HUA723020ALA641 drives just haven't put another in yet too lazy to copy all the data off the Seagate i been using it as a computer backup and download drive. The HUA723020ALA641 was bummed in the 343 it had a weird pause and restart problem and they also are hot drives and have issues with some hardware in Dell & HP machines. But in the 320 it is great fast and solid so far.

Just installed new 3TB HGST. It took a few reseat of the drive and transfer between the two slots before getting detected. Finally able to get it detected after installing it on HDD-Right slot while current 2TB Seagate is on the other slot. It was the same configuration I first tried but did not work initially. Current setup is below:
